Hello friends,I meet some problems when handle glb models.
I have export some glb files from obj models by the babylonjs.serializers.min.js like those:
Then,I use this script to compress them:
gltf-pipeline -i Tile_+002_+002_L23_00113100.glb -o Tile_+002_+002_L23_00113100-draco.glb -d --draco.compressionLevel 10
The result is:
I found that,only ten persent volume is compressed.It is much smaller than the example on the draco official website!How could I find out what went wrong?
Otherwise,if I can’t further reduce the model volume,should I use the 90% glb file when it has a decode calculation process,or directly use the original glb exported by babylonjs？
The third question is, when I adjust the --draco.compressionLevel parameter from 0 to 10 the volume is not in reverse ratio,the glb with lower compression level may smaller than the higher one！Ant the compress time cost is not in direct ratio too:
Why is that?And which compression level should I choose？
